Broadmoor hospital siren test. The broadmoor siren. Every monday morning at ten o'clock the deafening sound of an air-raid siren disturbs the peace over a large area of the leafy commuter belt that is berkshire, uk. The signal sounds the familiar alternating high-low note, followed by a constant all-clear note five minutes later. It's not a re-enactment of the blitz; it's a test of the escape alarm at the local mental hospital, broadmoor.
An emergency siren, electronic. Rapidly switching 440 and 640 hz. Tones. Made in audacity, by me. Please, feel tree to use in any way, shape or form, but be sure to give me credit. Thanks!.
This is the same sound i recorded 6 years ago, back than i had just a very crappy microphone through my cellphone. Last year i bought an ipad, and i installed hokusai audio editor. This gave me a better way to record in higher quality. Still mono though, but it has less audio artifacts. This alarm is tested once every 3 months all over the swedish towns.
